The Jitsie block (or piston spacer) is a CNC machined aluminium piece
that fits in between the pistons of the disc brake caliper and prevents
the pistons from moving outwards during the bleed process.
Features:
* CNC machined from aluminium
* develop specifically for the Jitsie disc brake caliper
* note: always take out brake pads while bleeding to avoid risk of contaminating them with brake fluid
